The changing climate

Here is one explanation.

There is no question the world’s weather systems are changing. However, for folk who are not trained in this science it is all a bit mysterious. So thank goodness that The Conversation have not only got a scientist who does know what he is talking about but also they are very happy for it to be republished.

Atmospheric rivers are shifting poleward, reshaping global weather patterns

Atmospheric rivers – those long, narrow bands of water vapor in the sky that bring heavy rain and storms to the U.S. West Coast and many other regions – are shifting toward higher latitudes, and that’s changing weather patterns around the world.

The shift is worsening droughts in some regions, intensifying flooding in others, and putting water resources that many communities rely on at risk. When atmospheric rivers reach far northward into the Arctic, they can also melt sea ice, affecting the global climate.

In a new study published in Science Advances, University of California, Santa Barbara, climate scientist Qinghua Ding and I show that atmospheric rivers have shifted about 6 to 10 degrees toward the two poles over the past four decades.

Atmospheric rivers on the move

Atmospheric rivers aren’t just a U.S West Coast thing. They form in many parts of the world and provide over half of the mean annual runoff in these regions, including the U.S. Southeast coasts and West Coast, Southeast Asia, New Zealand, northern Spain, Portugal, the United Kingdom and south-central Chile.

California relies on atmospheric rivers for up to 50% of its yearly rainfall. A series of winter atmospheric rivers there can bring enough rain and snow to end a drought, as parts of the region saw in 2023.

While atmospheric rivers share a similar origin – moisture supply from the tropics – atmospheric instability of the jet stream allows them to curve poleward in different ways. No two atmospheric rivers are exactly alike.

What particularly interests climate scientists, including us, is the collective behavior of atmospheric rivers. Atmospheric rivers are commonly seen in the extratropics, a region between the latitudes of 30 and 50 degrees in both hemispheres that includes most of the continental U.S., southern Australia and Chile.

Our study shows that atmospheric rivers have been shifting poleward over the past four decades. In both hemispheres, activity has increased along 50 degrees north and 50 degrees south, while it has decreased along 30 degrees north and 30 degrees south since 1979. In North America, that means more atmospheric rivers drenching British Columbia and Alaska.

A global chain reaction

One main reason for this shift is changes in sea surface temperatures in the eastern tropical Pacific. Since 2000, waters in the eastern tropical Pacific have had a cooling tendency, which affects atmospheric circulation worldwide. This cooling, often associated with La Niña conditions, pushes atmospheric rivers toward the poles.

The poleward movement of atmospheric rivers can be explained as a chain of interconnected processes.

During La Niña conditions, when sea surface temperatures cool in the eastern tropical Pacific, the Walker circulation – giant loops of air that affect precipitation as they rise and fall over different parts of the tropics – strengthens over the western Pacific. This stronger circulation causes the tropical rainfall belt to expand. The expanded tropical rainfall, combined with changes in atmospheric eddy patterns, results in high-pressure anomalies and wind patterns that steer atmospheric rivers farther poleward.

An animation of satellite data shows sea surface temperatures changing over months along the equator in the eastern Pacific Ocean. When they're warmer than normal, that indicates El Niño forming. Cooler than normal indicates La Nina.
La Niña, with cooler water in the eastern Pacific, fades, and El Niño, with warmer water, starts to form in the tropical Pacific Ocean in 2023. NOAA Climate.gov

Conversely, during El Niño conditions, with warmer sea surface temperatures, the mechanism operates in the opposite direction, shifting atmospheric rivers so they don’t travel as far from the equator.

The shifts raise important questions about how climate models predict future changes in atmospheric rivers. Current models might underestimate natural variability, such as changes in the tropical Pacific, which can significantly affect atmospheric rivers. Understanding this connection can help forecasters make better predictions about future rainfall patterns and water availability.

Why does this poleward shift matter?

A shift in atmospheric rivers can have big effects on local climates.

In the subtropics, where atmospheric rivers are becoming less common, the result could be longer droughts and less water. Many areas, such as California and southern Brazil, depend on atmospheric rivers for rainfall to fill reservoirs and support farming. Without this moisture, these areas could face more water shortages, putting stress on communities, farms and ecosystems.

In higher latitudes, atmospheric rivers moving poleward could lead to more extreme rainfall, flooding and landslides in places such as the U.S. Pacific Northwest, Europe, and even in polar regions.

A long narrow band of moisture sweeps up toward California, crossing hundreds of miles of Pacific Ocean.

In the Arctic, more atmospheric rivers could speed up sea ice melting, adding to global warming and affecting animals that rely on the ice. An earlier study I was involved in found that the trend in summertime atmospheric river activity may contribute 36% of the increasing trend in summer moisture over the entire Arctic since 1979.

What it means for the future

So far, the shifts we have seen still mainly reflect changes due to natural processes, but human-induced global warming also plays a role. Global warming is expected to increase the overall frequency and intensity of atmospheric rivers because a warmer atmosphere can hold more moisture.

How that might change as the planet continues to warm is less clear. Predicting future changes remains uncertain due largely to the difficulty in predicting the natural swings between El Niño and La Niña, which play an important role in atmospheric river shifts.

As the world gets warmer, atmospheric rivers – and the critical rains they bring – will keep changing course. We need to understand and adapt to these changes so communities can keep thriving in a changing climate.

Centuries ago, the Maya storm god Huracán taught that when we damage nature, we damage ourselves

The ancient Maya believed that everything in the universe, from the natural world to everyday experiences, was part of a single, powerful spiritual force. They were not polytheists who worshipped distinct gods but pantheists who believed that various gods were just manifestations of that force.

Some of the best evidence for this comes from the behavior of two of the most powerful beings of the Maya world: The first is a creator god whose name is still spoken by millions of people every fall – Huracán, or “Hurricane.” The second is a god of lightning, K’awiil, from the early first millennium C.E.

As a scholar of the Indigenous religions of the Americas, I recognize that these beings, though separated by over 1,000 years, are related and can teach us something about our relationship to the natural world.

Huracán, the ‘Heart of Sky’

Huracán was once a god of the K’iche’, one of the Maya peoples who today live in the southern highlands of Guatemala. He was one of the main characters of the Popol Vuh, a religious text from the 16th century. His name probably originated in the Caribbean, where other cultures used it to describe the destructive power of storms.

The K’iche’ associated Huracán, which means “one leg” in the K’iche’ language, with weather. He was also their primary god of creation and was responsible for all life on earth, including humans.

Because of this, he was sometimes known as U K’ux K’aj, or “Heart of Sky.” In the K’iche’ language, k’ux was not only the heart but also the spark of life, the source of all thought and imagination.

Yet, Huracán was not perfect. He made mistakes and occasionally destroyed his creations. He was also a jealous god who damaged humans so they would not be his equal. In one such episode, he is believed to have clouded their vision, thus preventing them from being able to see the universe as he saw it.

Huracán was one being who existed as three distinct persons: Thunderbolt Huracán, Youngest Thunderbolt and Sudden Thunderbolt. Each of them embodied different types of lightning, ranging from enormous bolts to small or sudden flashes of light.

Despite the fact that he was a god of lightning, there were no strict boundaries between his powers and the powers of other gods. Any of them might wield lightning, or create humanity, or destroy the Earth.

Another storm god

The Popol Vuh implies that gods could mix and match their powers at will, but other religious texts are more explicit. One thousand years before the Popol Vuh was written, there was a different version of Huracán called K’awiil. During the first millennium, people from southern Mexico to western Honduras venerated him as a god of agriculture, lightning and royalty.

The ancient Maya god K’awiil, left, had an ax or torch in his forehead as well as a snake in place of his right leg. K5164 from the Justin Kerr Maya archive, Dumbarton Oaks, Trustees for Harvard University, Washington, D.C.

Illustrations of K’awiil can be found everywhere on Maya pottery and sculpture. He is almost human in many depictions: He has two arms, two legs and a head. But his forehead is the spark of life – and so it usually has something that produces sparks sticking out of it, such as a flint ax or a flaming torch. And one of his legs does not end in a foot. In its place is a snake with an open mouth, from which another being often emerges.

Indeed, rulers, and even gods, once performed ceremonies to K’awiil in order to try and summon other supernatural beings. As personified lightning, he was believed to create portals to other worlds, through which ancestors and gods might travel.

Representation of power

For the ancient Maya, lightning was raw power. It was basic to all creation and destruction. Because of this, the ancient Maya carved and painted many images of K’awiil. Scribes wrote about him as a kind of energy – as a god with “many faces,” or even as part of a triad similar to Huracán.

He was everywhere in ancient Maya art. But he was also never the focus. As raw power, he was used by others to achieve their ends.

Rain gods, for example, wielded him like an ax, creating sparks in seeds for agriculture. Conjurers summoned him, but mostly because they believed he could help them communicate with other creatures from other worlds. Rulers even carried scepters fashioned in his image during dances and processions.

Moreover, Maya artists always had K’awiil doing something or being used to make something happen. They believed that power was something you did, not something you had. Like a bolt of lightning, power was always shifting, always in motion.

An interdependent world

Because of this, the ancient Maya thought that reality was not static but ever-changing. There were no strict boundaries between space and time, the forces of nature or the animate and inanimate worlds.

Everything was malleable and interdependent. Theoretically, anything could become anything else – and everything was potentially a living being. Rulers could ritually turn themselves into gods. Sculptures could be hacked to death. Even natural features such as mountains were believed to be alive.

These ideas – common in pantheist societies – persist today in some communities in the Americas.

They were once mainstream, however, and were a part of K’iche’ religion 1,000 years later, in the time of Huracán. One of the lessons of the Popol Vuh, told during the episode where Huracán clouds human vision, is that the human perception of reality is an illusion.

The illusion is not that different things exist. Rather it is that they exist independent from one another. Huracán, in this sense, damaged himself by damaging his creations.

Hurricane season every year should remind us that human beings are not independent from nature but part of it. And like Hurácan, when we damage nature, we damage ourselves.

ooOOoo

It is such a powerful message, that when we damage nature, we damage ourselves.

But I am unaware, no we are both unaware of a solution, and there doesn’t appear to be a government desire to make this the number one topic.

Please, if there is anyone who reads this post and has a more positive message then we would be very keen to hear from you.

Atheism

A fascinating article makes a fundamental point.

My mother and father were atheists so when I was born in 1944 it was obvious that I would be brought up as an atheist. Same for my sister, Elizabeth, born in 1948. It was amazing that when I met Jean in Mexico in 2007 that she, too, was an atheist. That was on top of the fact that we were both born in North London some 26 miles apart. Talk about fate!

So naturally my attention was drawn to a recent article in Free Enquiry magazine, Thinking Made Me an Atheist.

That article opens as follows:

I was abused as a child. The abuse to which I was subjected is called “child indoctrination,” a type of brainwashing considered noble and necessary and, therefore, the most natural thing in the world.

My mother took me to the Seventh-day Adventist Church, an American denomination known for keeping the Sabbath and emphasizing the advent, or return, of Jesus. Adventists boast that they are the only ones to interpret the Bible the way its author wanted. Consequently, they deem themselves the most special creatures to God—so special that they’ll soon arouse the envy and wrath of all other denominations and religions, which, under the command of the beasts of Revelation (the American government and the Catholic Church), will persecute them. Adventists believe that the Earth was created in six days, that it is 6,000 years old, and that dinosaurs are extinct because they were too big to be saved on Noah’s ark.

It closes thus:

I don’t want to believe; I want to know. Atheism is a natural result of intellectual honesty.

The author of the article, Paulo Bittencourt is described as:

Paulo Bittencourt was born in Castro, Brazil, spent his childhood in Rio de Janeiro, and studied theology in São Paulo. Close to becoming a pastor, he went on an adventure to Europe and ended up settling in Austria, where he trained as an opera singer. Bittencourt is the author of the books Liberated from Religion: The Inestimable Pleasure of Being a Freethinker and Wasting Time on God: Why I Am an Atheist.

So once again, do read this article.

We sincerely believe there is no god!

Best Dogs for Seniors

Medically Reviewed by Poonam Sachdev on October 12, 2023

Written by WebMD Editorial Contributors

Any dog owner can tell you there’s nothing like having a loyal companion. Dogs are good pets for people of any age, as long as you choose the right dog for your lifestyle.

If you’re an older adult looking to find a furry, four-legged friend, here are a few things you should consider. 

Why Get a Dog?

It’s a big responsibility, but the benefits are worth the work. Dogs can give you joy, companionship, and unconditional love. They can bring warmth and comfort into your life.

Better health. Decades of studies have shown the health benefits of spending time with dogs. Dog owners tend to have better heart and blood vessel health, including lower blood pressure, than those who don’t have a pet pup. That’s because dogs get people moving. Walking a dog regularly can help you boost how much exercise you get each day.

Less lonely. Dogs offer companionship just by being around. They might also help you be more social. Taking your dog on walks gives you a chance to meet neighbors or other canine owners at the local dog park.

Much happier. Looking at your dog can release a hormone that makes you feel happier. Science shows that gazing into your dog’s eye releases oxytocin. Known as the love hormone, oxytocin quickly boosts your mood.

Caring for a Dog

Before you get a furry pal, you should think about what you can offer the dog, as well as what they can offer you. You want to make sure to choose a dog that will be happy with the kind of life you lead. Consider these things when you start looking for a new pet.

Space. How much room do you have indoors and outdoors? You need to pick a dog that will be happy with the space you have to offer. 

Exercise. Some dogs need a lot of exercise, while others are happy hanging out on the couch all day. Think about how much exercise time you can give your pup. Also, think about how fit you are. You may not want a large, strong dog that could tug hard on the leash and cause you to get hurt on a walk.

Cost. All dogs need vet care, food, and toys. If they need a lot of grooming, you need to consider paying a professional groomer.

Age. Puppies are cute, but they’re also a lot of work. Older dogs may already have some training, but they might be set in their ways. Spend some time thinking about what you’re willing to accept in dog behavior.

Best Breeds for Seniors

Here are a few breeds that are natural choices for older adults.

Bichon Frise. These dogs are very small and cute. Their fluffy coats need regular grooming. They’re happy in small homes and apartments, and they only need moderate exercise.

Cocker spaniels. These dogs are known for their beautiful, soft coats, which need regular grooming. They’re gentle and friendly, and usually weigh under 30 pounds. They need regular walks to stay fit, but they aren’t highly energetic.

Beagles. They’re small, smart, and make wonderful companions. Their short coats are easy to groom. Beagles are energetic and need a lot of exercise every day.

Greyhounds. They can run fast, but they don’t always want to. They’re happiest lounging around indoors, but they need walks to stay fit. They’re large, usually weighing around 60 pounds, but they have short coats that don’t require a lot of grooming.

Pugs. These happy little dogs make great companions. They’re usually around 15 pounds and have short, easy-to-groom coats. They need more exercise than they want because they’re prone to be overweight. Regular walks can take care of that.

If you’re an older adult looking for a four-legged companion, you can speak to a veterinarian or a dog trainer in your area for more information. They can help you choose the perfect pet.

ooOOoo

I am certain there are many people who will find this a practical help in deciding what dog to get.

In my own case we currently have two dogs, Cleo and Oliver, and I frequently ponder on what Jean and I do when the last of them dies.

This article reminds me and Jean that at whatever age we are it is better to have a dog than not!

The Heart Wall in London

I love this!

I am writing this having listened to a programme on BBC Radio 4. (Was broadcast on Radio 4 on Tuesday, August 13th.) It shows how many, many people can have a really positive response to a dastardly negative occurrence such as the Covid outbreak or a pandemic.

Why are those lost to COVID not formally memorialised? How politics shapes what we remember

Mark Honigsbaum, City, University of London

Every Friday, volunteers gather on the Albert Embankment at the River Thames in London to lovingly retouch thousands of red hearts inscribed on a Portland stone wall directly opposite the Houses of Parliament. Each heart is dedicated to a British victim of COVID. It is a deeply social space – a place where the COVID bereaved come together to honour their dead and share memories.

The so-called National Covid Memorial Wall is not, however, officially sanctioned. In fact, ever since activists from COVID-19 Bereaved Families for Justice (CBFFJ) daubed the first hearts on the wall in March 2021 it has been a thorn in the side of the authorities.

Featured in the media whenever there is a new revelation about partygate, the wall is a symbol of the government’s blundering response to the pandemic and an implicit rebuke to former prime minister Boris Johnson and other government staff who breached coronavirus restrictions.

As one writer put it, viewed from parliament the hearts resemble “a reproachful smear of blood”. Little wonder that the only time Johnson visited the wall was under the cover of darkness to avoid the TV cameras. His successor Rishi Sunak has been similarly reluctant to acknowledge the wall or say what might take its place as a more formal memorial to those lost in the pandemic.

Though in April the UK Commission on COVID Commemoration presented Sunak with a report on how the pandemic should be remembered, Sunak has yet to reveal the commission’s recommendations.

Lady Heather Hallett, the former high court judge who chairs the public inquiry into COVID, has attempted to acknowledge the trauma of the bereaved by commissioning a tapestry to capture the experiences of people who “suffered hardship and loss” during the pandemic. Yet such initiatives are no substitute for state-sponsored memorials.

What is remembered and what is forgotten?

This political vacuum is odd when you consider that the United Kingdom, like other countries, engages in many other commemorative activities central to national identity. The fallen of the first world war and other military conflicts are commemorated in a Remembrance Sunday ceremony held every November at the Cenotaph in London, for example.

But while wars lend themselves to compelling moral narratives, it is difficult to locate meaning in the random mutations of a virus. And while wars draw on a familiar repertoire of symbols and rituals, pandemics have few templates.

For instance, despite killing more than 50 million globally, there are virtually no memorials to the 1918-1919 “Spanish” influenza pandemic. Nor does the UK have a memorial to victims of HIV/AIDS. As the memory studies scholar Astrid Erll puts it, pandemics have not been sufficiently “mediated” in collective memory.

As a rule, they do not feature in famous paintings, novels or films or in the oral histories passed down as part of family lore. Nor are they able to draw on familiar cultural materials such as poppies, gun carriages, catafalques and royal salutes. Without such symbols and schemata, Erll argues, we struggle to incorporate pandemics into our collective remembering systems.

This lacuna was brought home to me last September when tens of thousands of Britons flocked to the south bank of the Thames to pay their respects to Britain’s longest serving monarch. By coincidence, the police directed the queue for the late Queen’s lying-in-state in Westminster Hall over Lambeth Bridge and along Albert Embankment.

But few of the people I spoke to in the queue seemed to realise what the hearts signified. It was as if the spectacle of a royal death had eclipsed the suffering of the COVID bereaved, rendering the wall all but invisible.

Waiting for answers

Another place where the pandemic could be embedded in collective memory is at the public inquiry. Opening the preliminary hearing last October into the UK’s resilience and preparedness for a pandemic, Lady Hallett promised to put the estimated 6.8 million Britons mourning the death of a family member or friend to COVID at the heart of the legal process. “I am listening to them; their loss will be recognised,” she said.

But though Lady Hallett has strategically placed photographs of the hearts throughout the inquiry’s offices in Bayswater and has invited the bereaved to relate their experiences to “Every Story Matters”, the hearing room is dominated by ranks of lawyers. And except when a prominent minister or official is called to testify, the proceedings rarely make the news.

This is partly the fault of the inquiry process itself. The hearings are due to last until 2025, with the report on the first stage of the process not expected until the summer of 2024. As Lucy Easthope, an emergency planner and veteran of several disasters, puts it: “one of the most painful frustrations of the inquiry will be temporal. It will simply take too long.”

The inquiry has also been beset by bureaucratic obfuscation, not least by the Cabinet Office which attempted (unsuccessfully in the end) to block the release of WhatsApp messages relating to discussions between ministers and Downing Street officials in the run-up to lockdown.

To the inquiry’s critics, the obvious parallel is with the Grenfell inquiry, which promised to “learn lessons” from the devastating fire that engulfed the west London tower in 2017 but has so far ended up blurring the lines of corporate responsibility and forestalling a political reckoning.

The real work of holding the government to account and making memories takes place every Friday at the wall and the other places where people come together to spontaneously mourn and remember absent loved ones. These are the lives that demand to be “seen”. They are the ghosts that haunt our amnesic political culture.

Little Dog Forms Remarkable Bond With A Friendly Wild Shark

They meet up almost every day.

By Alana Francis-Crow

Published on Aug 16, 2024

For most dogs, their friend groups usually consist of a mix of humans and other dogs. But Lili, a 3-year-old dog who lives on a French Polynesian atoll called Fakarava, isn’t like most other dogs. She prefers friends who have gills and fins. In fact, her very best friend is a shark.

Ever since Lili’s mom, Emmanuelle Larchet, adopted Lili, she’s known that her dog has an affinity for all things aquatic. She started swimming in the lagoon near Larchet’s house when she was only a month old.

“She’s really a water dog,” Larchet told The Dodo.

There are around 100 sharks who live in this lagoon near Larchet’s house. So when Lili swims in the water there, she’s surrounded by them. While many dog parents would be terrified to see their dog swimming amongst sharks, Larchet knows that the sharks Lili swims with are nurse sharks, who are actually very docile creatures.

“We call them sea puppies because [they’re] like dogs, actually … They are very nice,” Larchet said.

Larchet likes to joke that when Lili swims around with her shark friends, it’s sea puppies meeting earth puppies.

Over the years Lili has been swimming in the lagoon, there’s one shark in particular she’s grown especially close with. His name is Sharky, and he and Lili visit each other almost every day. Larchet and Lili are able to recognize Sharky because he has a special marking on one of his fins.

Lili and Sharky like to explore their lagoon together. They enjoy splashing around in the warm, clear water.

“He comes to say hello every time she sees him,” Larchet said.

Even though Lili and Larchet are best friends themselves, Larchet is more than happy to share her Lili with Sharky. And even though Larchet watches Lili hang out with her shark friends all the time, it never gets old seeing them spend time together.

“[When] I see her swimming with Sharky, [I’m] so happy,” Larchet said.

Couple Hires Dog To Film Their Wedding — And The Results Are Simply Perfect

Such a great idea ❤️

By Alana Francis-Crow

Published on Aug 23, 2024

Ellie Woods’ family dog Bobby has always been an important part of her love story with her wife Georgie Woods. When Ellie brought Georgie home for the first time, the family member she was most anxious for Georgie to meet was Bobby.

When the couple got engaged and started planning their wedding, they decided it would be fun to try to document the wedding from Bobby’s unique perspective. So right before the ceremony started, they attached a GoPro to Bobby’s back and then set him loose.

For some dogs, walking around with a camera on their back might take some getting used to — but not for Bobby. He immediately felt comfortable.

“He loves being the center of attention,” Georgie told The Dodo. “He just loved it.”

Georgie and Ellie said having Bobby at their wedding was incredibly meaningful for them.

@SASHALEEPHOTOGRAPHY


“Animals are really important to queer couples,” Ellie said. “[I]t was so important to have him … as part of our big day.

When the newlyweds sat down to watch the footage Bobby had captured, what they saw surprised and delighted them. The GoPro had caught Bobby stealing hors d’oeuvres and even walking in on Georgie’s sister in the bathroom. While Bobby is an expert videographer, he is still a dog, after all.

Of course, Bobby’s camera recorded much more than shenanigans. Georgie and Ellie loved watching themselves walk down the aisle together from Bobby’s perspective.

“It captured some really special moments,” Ellie said. “[W]e couldn’t be happier for how it came out because it’s just so organic and such an interesting, different perspective.”

Dogs are just incredible. As much as I have already said that, time and time again there comes a story that just reinforces that previous sentence.

The climate is changing so fast that we haven’t seen how bad extreme weather could get

Simon H. Lee, University of St Andrews; Hayley J. Fowler, Newcastle University, and Paul Davies, Newcastle University

Published: July 30, 2024

Extreme weather is by definition rare on our planet. Ferocious storms, searing heatwaves and biting cold snaps illustrate what the climate is capable of at its worst. However, since Earth’s climate is rapidly warming, predominantly due to fossil fuel burning, the range of possible weather conditions, including extremes, is changing.

Scientists define “climate” as the distribution of possible weather events observed over a length of time, such as the range of temperatures, rainfall totals or hours of sunshine. From this they construct statistical measures, such as the average (or normal) temperature. Weather varies on several timescales – from seconds to decades – so the longer the period over which the climate is analysed, the more accurately these analyses capture the infinite range of possible configurations of the atmosphere.

Typically, meteorologists and climate scientists use a 30-year period to represent the climate, which is updated every ten years. The most recent climate period is 1991-2020. The difference between each successive 30-year climate period serves as a very literal record of climate change.

This way of thinking about the climate falls short when the climate itself is rapidly changing. Global average temperatures have increased at around 0.2°C per decade over the past 30 years, meaning that the global climate of 1991 was around 0.6°C cooler than that in 2020 (when accounting for other year-to-year fluctuations), and even more so than the present day.

A moving target for climate modellers

If the climate is a range of possible weather events, then this rapid change has two implications. First, it means that part of the distribution of weather events comprising a 30-year climate period occurred in a very different background global climate: for example, northerly winds in the 1990s were much colder than those in the 2020s in north-west Europe, thanks to the Arctic warming nearly four times faster than the global average. Statistics from three decades ago no longer represent what is possible in the present day.

Second, the rapidly changing climate means we have not necessarily experienced the extremes that modern-day atmospheric and oceanic warmth can produce. In a stable climate, scientists would have multiple decades for the atmosphere to get into its various configurations and drive extreme events, such as heatwaves, floods or droughts. We could then use these observations to build up an understanding of what the climate is capable of. But in our rapidly changing climate, we effectively have only a few years – not enough to experience everything the climate has to offer.

Extreme weather events require what meteorologists might call a “perfect storm”. For example, extreme heat in the UK typically requires the northward movement of an air mass from Africa combined with clear skies, dry soils and a stable atmosphere to prevent thunderstorms forming which tend to dissipate heat.

Such “perfect” conditions are intrinsically unlikely, and many years can pass without them occurring – all while the climate continues to change in the background. Based on an understanding of observations alone, this can leave us woefully underprepared for what the climate can now do, should the right weather conditions all come together at once.

Startling recent examples include the extreme heatwave in the Pacific north-west of North America in 2021, in which temperatures exceeded the previous Canadian record maximum by 4.6°C. Another is the occurrence of 40°C in the UK in summer 2022, which exceeded the previous UK record maximum set only three years earlier by 1.6°C. This is part of the reason why the true impact of a fixed amount of global warming is only evident after several decades, but of course – since the climate is changing rapidly – we cannot use this method anymore.

Playing with fire

To better understand these extremes, scientists can use ensembles: many runs of the same weather or climate model that each slightly differ to show a range of plausible outcomes. Ensembles are routinely used in weather prediction, but can also be used to assess extreme events which could happen even if they do not actually happen at the time.

When 40°C first appeared in ensemble forecasts for the UK before the July 2022 heatwave, it revealed the kind of extreme weather that is possible in the current climate. Even if it had not come to fruition, its mere appearance in the models showed that the previously unthinkable was now possible. In the event, several naturally occurring atmospheric factors combined with background climate warming to generate the record-shattering heat on July 19 that year.

Later in summer 2022, after the first occurrence of 40°C, some ensemble weather forecasts for the UK showed a situation in which 40°C could be reached on multiple consecutive days. This would have posed an unprecedented threat to public health and infrastructure in the UK. Unlike the previous month, this event did not come to pass, and was quickly forgotten – but it shouldn’t have been.

It is not certain whether these model simulations correctly represent the processes involved in producing extreme heat. Even so, we must heed the warning signs.

Despite a record-warm planet, summer 2024 in the UK has been relatively cool so far. The past two years have seen global temperatures far above anything previously observed, and so potential extremes have probably shifted even further from what we have so far experienced.

Just as was the case in August 2022, we’ve got away with it for now – but we might not be so lucky next time.

That last sentence says it all: “Just as was the case in August 2022, we’ve got away with it for now – but we might not be so lucky next time.”

I am giving a talk, The Next Ten Years, next Saturday to our local Freethinkers group in Grants Pass. Close to the start of the presentation I say: “The Global Temperature anomaly, as of last year, 2023, is 1.17 C, 2.11 F, above the long-term average from 1951 to 1980. The 10 most recent years are the warmest years on record.“

Finally, I am getting on in age and part of me wants to die, hopefully naturally, before more climate extremes are reached, but then another part of me would like to experience it!

Essentially, life is about play

We take our decision from watching the animal kingdom.

A recent post in The Conversation provides the article for today’s blog post.

At its core, life is all about play − just look at the animal kingdom

At Cambridge University Library, along with all the books, maps and manuscripts, there’s a child’s drawing that curators have titled “The Battle of the Fruit and Vegetable Soldiers.”

The drawing depicts a turbaned cavalry soldier facing off against an English dragoon. It’s a bit trippy: The British soldier sits astride a carrot, and the turbaned soldier rides a grape. Both carrot and grape are fitted with horses’ heads and stick appendages.

It’s thought to be the work of Francis Darwin, the seventh child of British naturalist Charles Darwin and his wife, Emma, and appears to have been made in 1857, when Frank would have been 10 or 11. And it’s drawn on the back of a page of a draft of “On the Origin of Species,” Darwin’s masterwork and the foundational text of evolutionary biology. The few sheets of the draft that survive are pages Darwin gave to his children to use for drawing paper.

Darwin’s biographers have long recognized that play was important in his personal and familial life. The Georgian manor in which he and Emma raised their 10 children was furnished with a rope swing hung over the first-floor landing and a portable wooden slide that could be laid over the main stairway. The gardens and surrounding countryside served as an open-air laboratory and playground.

Play also has a role in Darwin’s theory of natural selection. As I explain in my new book, “Kingdom of Play: What Ball-bouncing Octopuses, Belly-flopping Monkeys, and Mud-sliding Elephants Reveal about Life Itself,” there are many similarities – so many that if you could distill the processes of natural selection into a single behavior, that behavior would be play.

No goal, no direction

Natural selection is the process by which organisms that are best adapted to their environments are more likely to survive, and so able to pass on the characteristics that helped them thrive to their offspring. It is undirected: In Darwin’s words, it “includes no necessary and universal law of advancement or development.”

Through natural selection, the rock pocket mouse has evolved a coat color that hides it from predators in the desert Southwest.

In contrast to foraging and hunting – behaviors with clearly defined goals – play is likewise undirected. When a pony frolics in a field, a dog wrestles with a stick or chimpanzees chase each other, they act with no goal in mind.

Natural selection is utterly provisional: The evolution of any organism responds to whatever conditions are present at a given place and time. Likewise, animals at play are acting provisionally. They constantly adjust their movements in response to changes in circumstances. Playing squirrels, faced with obstacles such as falling branches or other squirrels, nimbly alter their tactics and routes.

Natural selection is open-ended. The forms of life are not fixed, but continually evolving. Play, too, is open-ended. Animals begin a play session with no plan of when to end it. Two dogs play-fighting, for instance, cease playing only when one is injured, exhausted or simply loses interest.

Natural selection also is wasteful, as Darwin acknowledged. “Many more individuals of each species are born than can possibly survive,” he wrote. But in the long term, he allowed, such profligacy could produce adaptations that enable an evolutionary line to become “more fit.”

Keepers noticed that Shanthi, a 36-year-old elephant at the Smithsonian national zoo, liked to make noise with objects, so they gave her horns, harmonicas and other noisemakers.

Play is likewise profligate. It requires an animal to expend time and energy that perhaps would be better devoted to behaviors such as foraging and hunting that could aid survival.

And that profligacy is also advantageous. Animals forage and hunt in specific ways that don’t typically change. But an animal at play is far more likely to innovate – and some of its innovations may in time be adapted into new ways to forage and hunt.

Competing and cooperating

As Darwin first framed it, the “struggle for existence” was by and large a competition. But in the 1860s, Russian naturalist Pyotr Kropotkin’s observations of birds and fallow deer led him to conclude that many species were “the most numerous and the most prosperous” because natural selection also selects for cooperation.

Scientists confirmed Kroptokin’s hypothesis in the 20th century, discovering all manner of cooperation, not only between members of the same species but between members of different species. For example, clown fish are immune to anemone stings; they nestle in anemone tentacles for protection and, in return, keep the anemones free of parasites, provide nutrients and drive away predators.

Play likewise utilizes both competition and cooperation. Two dogs play-fighting are certainly competing, yet to sustain their play, they must cooperate. They often reverse roles: A dog with the advantage of position might suddenly surrender that advantage and roll over on its back. If one bites harder than intended, it is likely to retreat and perform a play bow – saying, in effect, “My bad. I hope we can keep playing.”

River otters at the Oregon Zoo repeatedly separate and reunite while playing in a tub of ice.

Natural selection and play also may both employ deception. From butterflies colored to resemble toxic species to wild cats that squeal like distressed baby monkeys, many organisms use mimicry to deceive their prey, predators and rivals. Play – specifically, play-fighting – similarly offers animals opportunities to learn about and practice deception.

To live is to play

Darwin wrote that natural selection creates “endless forms most beautiful and most wonderful.” Play also creates beauty in countless ways, from the aerial acrobatics of birds of prey to the arcing, twisting leaps of dolphins.

In 1973, Ukrainian-American geneticist Theodosius Dobzhansky published an essay with the take-no-prisoners title “Nothing in Biology Makes Sense Except in the Light of Evolution.” Many biologists would agree. Perhaps the most satisfying definition of life attends not to what it is but to what it does – which is to say, life is what evolves by natural selection.

And since natural selection shares so many features with play, we may with some justification maintain that life, in a most fundamental sense, is playful.

Prof. Toomey’s analysis is spot-on.

All of life involves some form of play.

Dogs can smell our human stress

An article from Live Science tells all.

Dogs can smell their humans’ stress, and it makes them sad.

Humans and dogs have been close companions for perhaps 30,000 years, according to anthropological and DNA evidence. So it would make sense that dogs would be uniquely qualified to interpret human emotion. They have evolved to read verbal and visual cues from their owners, and previous research has shown that with their acute sense of smell, they can even detect the odor of stress in human sweat. Now researchers have found that not only can dogs smell stress—in this case represented by higher levels of the hormone cortisol—they also react to it emotionally.

For the new study, published Monday in Scientific Reports, scientists at the University of Bristol in England recruited 18 dogs of varying breeds, along with their owners. Eleven volunteers who were unfamiliar to the dogs were put through a stress test involving public speaking and arithmetic while samples of their underarm sweat were gathered on pieces of cloth. Next, the human participants underwent a relaxation exercise that included watching a nature video on a beanbag chair under dim lighting, after which new sweat samples were taken. Sweat samples from three of these volunteers were used in the study.

Participating canines were put into three groups and smelled sweat samples from one of the three volunteers. Prior to doing so, the dogs were trained to know that a food bowl at one location contained a treat and that a bowl at another location did not. During testing, bowls that did not contain a treat were sometimes placed in one of three “ambiguous” locations. In one testing session, when the dogs smelled the sample from a stressed volunteer, compared with the scent of a cloth without a sample, they were less likely to approach the bowl in one of the ambiguous locations, suggesting that they thought this bowl did not contain a treat. Previous research has shown that an expectation of a negative outcome reflects a down mood in dogs.

The results imply that when dogs are around stressed individuals, they’re more pessimistic about uncertain situations, whereas proximity to people with the relaxed odor does not have this effect, says Zoe Parr-Cortes, lead study author and a Ph.D. student at Bristol Veterinary School at the University of Bristol. “For thousands of years, dogs have learned to live with us, and a lot of their evolution has been alongside us. Both humans and dogs are social animals, and there’s an emotional contagion between us,” she says. “Being able to sense stress from another member of the pack was likely beneficial because it alerted them of a threat that another member of the group had already detected.”

The fact that the odor came from an individual who was unfamiliar to the dogs speaks to the importance of smell for the animals and to the way it affects emotions in such practical situations, says Katherine A. Houpt, a professor emeritus of behavioral medicine at Cornell University’s College of Veterinary Medicine. Houpt, who was not involved in the new study, suggests that the smell of stress may have reduced the dogs’ hunger because it’s known to impact appetite. “It might not be that it’s changing their decision-making but more that it’s changing their motivation for food,” she says. “It makes sense because when you’re super stressed, you’re not quite as interested in that candy bar.”

This research, Houpt adds, shows that dogs have empathy based on smell in addition to visual and verbal cues. And when you’re stressed, that could translate into behaviors that your dog doesn’t normally display, she says. What’s more, it leaves us to wonder how stress impacts the animals under the more intense weight of an anxious owner. “If the dogs are responding to more mild stress like this, I’d be interested to see how they responded to something more serious like an impending tornado, losing your job or failing a test,” Houpt says. “One would expect the dog to be even more attuned to an actual threat.”

Dogs are such perfect animals and Sara brings this out so well. As was pointed out in the article dogs have learned to live with us humans over thousands of years.

Well done, Sara!
